SPECIFIGATION forming part of Letters Patent No. 7d5,086, dated November24:, 1908.

Application filed March 21, 1908. Serial No. 148,872. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. WALKER, a citizen of the United States,and a resident of Harrison, in the county of Kiowa. and Territory ofOklahoma, have invented a new and Improved Machine for ConvertingMotion, of which the following is a full, clear, and exact description.

This invention relates to devices or mechanism forconverting rotarymotion into reciprocatory motion; and it consists, substantially, in themeans hereinafter particularly described and claimed.

Though applicable to different uses or purposes in the various arts, myimprovements have reference more especially to devices or mechanism forimparting reciprocatory motion to the rods or dashers of churns and likestructures; and the principal object of my invention is to providedevices or mechanism of this character which are simple both inconstruction and organization of the parts or ele ments thereof, besidesbeing thoroughly effective and reliable in use or operation.

A further object is to provide means whereby the operative elements orparts of the device or mechanism may be adjusted to different verticalheights to meet various requirements of use, and also to provide meansfor effecting operative connection between the elements or parts to bereciprocated and the driving member therefor. I

A still further object of the invention is to provide means whereby thereciprocated element or part may be adjusted to vary the effectivelength of stroke thereof, and also whereby ready connection anddisconnection of said element or part may be effected without thedisorganization of any of the remaining parts of the mechanism.

The above and additional objects are attained by means substantiallysuch as are illustrated in the accompanying drawings, in which-- Figure1 is a perspective View ofa machine constructed and organized inaccordance with my invention and from which the operation of the machinewill be clearly understood. Fig. 2 is a top plan view of the machine.Fig. 3 is a view in detail representing the means employed for effectingadjustable connection of the reciprocated element or part clamp by meansof which the reciprocated member is adjustably secured to the yoke.

Before proceeding with a more detailed description it may be stated thatmy improved machine is constructed of a suitable base and framework,such framework being preferably mounted at an elevation on suitablesupports therefor and being adjustable as to height, and supported bythis framework are the operative elements or parts of the machine, saidparts being adapted to be driven either by hand or from any suitablesource of motive power, the main elements or parts of the machine beingreadily detachable or removable either'in part or'in entirety, and theprincipal elements are also preferably adjustable, so as to meet thedifferent requirements of use to which the machine may be applied.

Specific reference being had to the several parts by the designatingcharacters marked thereon, 1 1 represent parallel members,

which are preferably rabbeted longitudinally at 2 2, by which to form aguideway for a platform 3, fitting between the vertical sides of saidmembers, and the structure thus set forth may be said to constitute thebase of my improved machine, the said platform 3 forming a convenientsupport for the body 4 of a churn having the usual rod 5 working throughthe top thereof. Mounted upon the horizontal portions of said basemembers 1 1 are suitable hollow posts or pillars 6, which are of equalheight and working verticallyin each of which is a rod 7, the upper endof which is screw-threaded at 8, said rods each being maintained invertical adjustments thereof by means of a set-screw 8 working in theside of its respective supporting-post.

- One of said rods passes through an opening therefor in an end of eachof the transverse portions 9 9 of the framework of the machine and alsothrough an opening therefor in the end of a member of a cross-brace l0,connecting said rods, as shown. The opposite innermost ones of the rodsreferred to likewise pass through openings near the inner ends oflongitudinal parallel members 11 of the sup porting-frame, (see Fig. 1,)the outer or forward ends of these members each being slotthreaded endsthereof being provided with butterfly-nuts 15, it being apparent that invirtue of this construction the said crosspiece 13 may be adjusted toanyposition within the limits afforded by the length of the slots, it beingalso mentioned at this point that the platform 3 may be moved toanydesired position longitudinally in the guide therefor formed by themembers 1 1 of the base. The upper screw-threaded portions of the rods[are each provided with a nut 16, and fitting over said screw-threadedportions of the outermost ones of the said rods 7 are the ends of across-brace 17, while similarly passing over the screw-threaded portionsof the innermost ones of said rods are the outer ends 18 of a similarcross-brace 19 of the framework. Likewise fitting upon the screwthreadedportions of the said rods 7 at the sides of the machine and resting uponthe upper surfaces of the ends ofsaid cross-braces 17 and 19 are upperparallel longitudinal members 20, all of these latterly-describedelements or parts being firmlysecured in place upon the rods by nuts 21or other tightening means therefor. Resting upon each of the lowerparallel longitudinal members 11 is an upright 22, located a suitabledistance from the forward or outer slotted end of said member, the saiduprights being rigidly secured in any suitable manner at 23 to the innerfree ends of the upper longitudinal parallel members 20, and at theupper ends of the uprights are secured the inner ends of right-angledextensions 24 thereof, each formed with a longitudinal slot 25, it beingapparent that said uprights are raised and lowered with remainingelements of the vertically-movable frame referred to. Connecting thefree ends of the said extensions 24 is an upper cross-piece 26, havingopenings at the ends through which pass the screws 27, entering the saidslots 25 from beneath, the threaded portions of said screws each beingprovided with an adjusting-nut 28, also preferably of the butterflytype. It will be observed that the lower and upper cross-pieces 13 and26 referred to are provided with coinciding openings through whichpasses the rod 5 of the churn or othercontrivauce, the rod being in thisway guided in its vertical reciprocating movements.

The cross-braces 17 and 19 are provided with bearings 29, having a.shaft 30, which may be driven in any suitable manner, but hereinrepresented as provided with an operating handle or crank 31, andmounted upon or carried by said shaft is a gear-wheel 32, which mesheswith a smaller gear-wheel or pinion 33, similarly mounted upon orcarried byanother parallel shaft 34, mounted in bearings on the saidcross-braces, this latter named shaft and provided at the innerextremity thereof with a sleeve 36, which is adjusted on this shaft, andthe same being secured at different adjustments by means of a set-screw37. (See Fig. 2.) The said sleeve 36 has centrally secured to the outerend thereof in any suitable way an eccentric or crank-disk 38, havingsecured to its outer face awrist-pin 39, to which is movably connectedone end of a link 40, the other end of which is in similar connection at41 with the lower end of a brace or yoke 42, which, as shown in Fig. 4,is concaved at 43, so as to snugly fit the side of the churn-rod 5 orother rod. Formed with or attached to the said brace or yoke 42 is atransverse bar 44,which is notched at 45 and 46 in the upper and loweredges thereof near each end, and forming adjustable connection betweenthe yoke and the rod is a spring-clamp specially devised by me,comprising a single piece of wire bent to form the coils 47 and 48,theportions 47 of the wire extending inwardly from the rod 5 and passingaround one end of the said cross-bar 44 and fitting the notches therein,(see Figs. 3 and 4,) while the terminals 49 and 50 of the coils passaround the rod 5 at the outer side thereof,as indicated in Fig. 3,thesaid terminal 50 then passing inwardly, substantially parallel with thesaid inwardly-extending portions 47 of the wire, thence brought aroundthe other end of the cross-bar 44 and fitting in the notches at that endof said bar, these said lower terminals being formed one with a crook51, which is engaged by the free end 52 of the other coil. It will beseen that in this way a ready means of attachment is had for the churnor other rod with the connections from the eccentric or crank disk, andit will also be seen that by loosening or detaching said spring-clampthe said rod 5 may be adjusted to any position vertically, the samebeing held in such position by again applying and securing the clamp inthe manner already stated.

From the foregoing it will be seen that the supportingframework of myimproved machine is adjustable vertically, and it will also be seen thatthe same is composedof few parts which are firmly united or securedtogether. Adjusting devices are also provided for different ones of themovable parts or elements of the machine, as herein specifically pointedout, and it is thought that the operation of the machine will be fullyunderstood.

I desire to add that while I have herein rep resented a certainpreferred form or embodiment of my invention, I am not limited to theprecise details thereof in practice, since immaterial changes thereinmay be resorted to coming within the scope of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a machine for converting rotary motion intoreciprocatory motion, a rotatable crank-disk having a link movablyconnected thereto, a yoke in movable connection with the link, andadapted for the partial reception of a device to be reciprocated, acrossbar attached to the yoke, and having oppositely-disposed notches inthe longer edges thereof, and a clamp for securing such device in placerelatively to the disk, said clamp being formed with spring-coils havingterminal portions constructed for separable engagement with each other,and said portions passing through said notches and extendingsubstantially longitudinally of said cross-bar.

2. In a machine for converting rotary motion into reciprocatory motion,a main supporting-frame, a frame vertically adjustable thereon, a shaftrotatably mounted in beareach other, said portions entering said notchesand extending alongside of said cross-bar.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
